Data Summary

The data summary section provides information on the total number of ImPACT tests administered from 2000 - 2020. The 2010 year displayed on the plots and tables represents the years 2000 - 2010. Within the data summary section, the total number of administered ImPACT tests is broken down by specific variables included in the ImPACT dataset, including participant gender, participant sport, and the type of test administered (e.g. baseline, post-injury 1, post-injury 2).

What is the percent increase in composite score from first baseline to second baseline administration?

To calculate the percent increase from first to second baseline test administrations, the dataset was manipulated in the following ways to isolate individuals who received two baseline test administrations:

  1. The test_type variable was filtered to only include valid baseline test administrations.

  2. Individuals who completed two baseline tests were identified and all other individuals were removed.

  3. The scores of the individuals’ five composite scores from both baselines were spread across the data set to appear on one row per individual.

  4. Individual data sets for the five composite scores were created to calculate the difference in baseline 2 to baseline 1 administration.

  5. Individuals who did not score higher on the second baseline administration were removed from the individual composite score data sets.

  6. The five composite score data sets were joined together to create a new data frame of individuals who achieved a positve gain on at least one composite score on the second baseline test administration.

  7. This combined data frame was filtered through to identify individuals who achieved a higher score on all five composite tests on the second baseline administration.

18,748 individuals completed two baseline assessments. 18,556 individuals achieved a higher score on at least one out of five composite scores on the second baseline assessment. 1,130 individuals achieved a higher score on all five composite scores on the second baseline assessment.

Five composite scores:

1. Verbal Memory Composite Score

2. Visual Memory Composite Score

3. Impulse Control Composite Score

4. Reaction Time Composite Score

5. Visual Motor Composite Score
